Neveros Wastewater Treatment Plant, San Dimas, Durango, Mexico

Neveros is a wastewater treatment plant located in the rural community of Neveros, within the municipality of San Dimas, Durango, Mexico. The plant serves a small population of approximately 392 residents, reflecting its role in a sparsely populated area of the Sierra Madre Occidental. The plant provides secondary treatment, which is the standard biological treatment process for municipal wastewater. With a designed capacity of 42.34 units and a current discharge volume of 37.15 units, the facility operates at a high utilization rate. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants. The treated effluent from Neveros likely drains into local streams that feed into the Presa El Palmito reservoir or the Río San Dimas, eventually reaching the Pacific Ocean via the Río Piaxtla basin. The surrounding ecosystem supports diverse wildlife, including pine-oak forests and species such as the thick-billed parrot and Mexican wolf.

The plant's discharge enters the Río San Dimas watershed, which flows into the Presa El Palmito and ultimately the Río Piaxtla, draining into the Pacific Ocean. This region is ecologically sensitive, supporting montane forests and aquatic habitats for endemic species. Proper treatment helps protect downstream water quality and biodiversity.
